Hello, Bob,
The camera export feature is now grouped with point cloud export, so you need to use "Export Points..." from "File" menu to export all required information. Cameras are saved when using PhotoScan structure, Chan, Boujou or Bundler file formats.
Please let me know if more information on specific file format is required.
Sorry for poor documentation on this topic.
Also you may be interested in the ongoing release of the PhotoScan Professional Edition, which will include such features as support for setting coordinate system, georeferencing, orthophoto export, DEM export and volume measurements. More information should become available during this week on AgiSoft web site.
With best regards,
